    Instead of using the coupler just match the wire and tape it together, like orange-orange, white orange-white orange, and so forth.
    You dont really need coupler, unless u wanna add different size of cables

    @Karan I needed shorter for my flash bracket. Also it’s pretty nice to only use the length I need.
